WRINGER ROLL Application filed May 29,

- The rotation of the driven roll is assured when a piece of cloth is held between the rolls, but when the rolls are wet with hot soapy water, the surface of the driving roll slides over the surface of the driven roll, rendering the wringer rollsuselessi When the edge of a garment is applied to the recess formed by the meeting peripheries of the rolls, when the rolls arewet with hot soapy water, the surface of the lower roll will slide on the garment and the upper roll, failing'to rotate the upper roll because of slippage of the lower roll thereon, failing to draw the garment into the wringer. Troublesome manipulation istherefore required tointroduce the garment betweenthe rolls to establish the frictionalrelation necessary for effecting the wringing, and the edge of the garment cannot be manually pressed between the rolls due to the pressure of the upper roll in power machines of this character. In order to restore the utility of the rolls, and enable the lower roll to rotate the upper roll, the rolls must be allowed to cool, or cold clear water must be thrown on the rolls.

The principal objects of my invention therefore are to assure frictional dliiving relation between driving and driven rolls, to

provide a frictional element on a relatively smooth wringer for effecting driving relation between a pair of rolls, to embody cooperating friction elements in a plurality of rolls, and to provide a driving element in a smooth resilient roll without reducing the efficiency of the roll or interfering with its normal operation, whereby rotation of one roll by another may be assured under all normal operating conditions.

In accomplishing these and other objects 1930; smu No. 456,928.

of my invention, I have provided improved details of structure, the preferred forms'of which: are illustrated in the accompanying drawing, wherein:

F ig. 1 is a perspective view of a clothes wringer and portions of a support, including rolls constructed'in accordance with my in vention, part ofa shieldbeing broken away to betterillustrate my invention.

Fig. 2 is an enlarged partly. sectional View of one end of a roll provided witha-fabric inlay.. i 1

Fig. 3 is an enlarged fragmentary section of a portion of a roll containing the inlay.

Referring in detail to the-drawing:

1.,clesignates generally a wringer frame, 2 a shaft rotatably supported by the wringer frame and connected in drivenrelation with actuating mechanism including a m'otor,,n0t shown, and'represented by the casing 3.-

The shaft comprises the supporting ele ment of a roll 4,-and a second roll 5 induct inga shaft 6 is rotatively supported by the frame above and parallel with the first roll and held; resiliently in engagement therewith by suitable means such as springs-,not shown. Each roll includes a relatively hard core portion 7 and a relativelysoft and come pressible resilient cylindrical facing element 8 having a smooth surface.

The "elements just described are in general those ordinarily found in Wringers mounted at the edge of a tub, and clothes washedin soapy water in the tub are delivered to the pair of rollsto be grasped by theoppositely rotating surfaces and'drawn therethrough for extractingwater from theclothes.

When the rolls are dry or are wet with cold: water, the lower roll will engage the upper rolllwith'suflicient friction to rotate the same. 0"

The presence :of a' piece of cloth'between the rolls also provides necessary friction'for:

enabling the lower roll toeifect rotation of.

the upper roll.

When a cloth or similar object is not-pres-- ent between the rolls, and hot' soapy clothes are being fed to the wringer, the surfaceof the; lower roll will slide'over the'upper roll Without efi'ectingrot-ation of the upper roll..

r so.-

My invention pertains particularly to means for assuring rotation of the upper roll by the lower roll, to draw clothes into the wringer, even when the rolls are wet with hot I preferably inlay a strip including fabric in one of the. rolls and provide a relatively shallow groove 10 in the roll to receive the strip, whereby the outer surface of the strip may lie in registry with the surface of the roll. The stripextends circumferentially of the roll entirely around the same, and is preferably located adjacent one'end of the roll.

,I further preferably install strips in the same positions on both of the rolls, so that the surfaces of the inlaid strips will engage, and form continuously operating and continuously engaged frictional surfaces on the rolls.

The strips consist preferably of resilient bodies including layers of cloth or gauze 11 imbedded in the bodies, whereby the threads of the gauze may lie on the surfaces of'the strips and as the strips wear, other threads will be exposed to provide the frictional surfaces.

In using a wringer having rolls constructed in accordance with my invention, for example two rolls having circumferential frictional strips adjacent similar ends as in Fig. 1, the upper roll will be constantly ro tated by the roll which is driven by the actuating mechanism of the machine. When the edge of a garment is held against the oppositely rotating surfaces of the rolls it will be drawn therebetween and the wringer will extract the water therefrom.

'However much the rolls-may be lubricated by hot soapy water the driving relation will not be affected and the wringer will always therefore operate without requiring special means or operations such as throwing cold Water on the rolls for setting up rotation of the upper roll and effecting engagement of agarment by the rolls.

Portions of the garments operated on by the wringer may pass between the inserted strips without damage to the garment or interference with the operation of the rolls, since the portions of the rolls which support the relatively thin resilient strips will yield to substantially the same extent as the portions not provided with strips.

Attention is further called to the fact that improved rolls provided with the elements described to assure driving'relation between the rolls will not readily break or tear and have surfaces that may easily be cleaned and that will not collect materials'from the 'water and clothes. Sanitary qualities are thus preserved and enhanced, as particularly desirable in a device of this character used in connection with clothes cleansing operations.

What I claim and. desire to secure by Letters Patent is: 1

1. A wringer roll including a yielding cylindrical core, a facing for the core having a greater degree of resiliency than the core, and a pluralityof layers'of fabric embedded in and covering the facing at one end of the roll, and having a greater coeflicient of friction than the exposed surface of the facing.

2. A wringer roll including a yielding cylindrical core, a facing for the core having a greater degree of resiliency than thecore, and a fabric ring inlayed in and covering a portion of the facing, and having a greater coefficient of friction than the exposed surface of the facing. 1 I o V 3. A wringer roll formed of resilient yielding material and a plurality. of threaded fabriclayers inset in and covering a portionof the roll to provide a continual frictional driving surface for the roll so that as'the strips wear, the threads on theinner strips will be exposed to provide additional frictional surfaces. v r

4. In a wringer roll having a yieldingresilient periphery, acylindrical fabric inset ring fixed to a portion of the resilient roll, and having a greater coefficient of friction thanthe surface of the roll to provide a driving surface for the roll. 5. In a wringer, a pairof contacting rolls having yielding resilient peripheries, and a cylindrical inset ring surrounding adjacent portionsjof each roll and having greater co efficient of friction than thesurface of the rolls when the rolls are wet with soapy water to effect driving relation between the rolls. 7

In testimony whereof I afiix my signature.
